IMPROVEMENT IN WASH-BOILER ATTACHMENTS.

Specification forming part of Letters Patent No. I5S,45S, dated January5, 1875; application filed December 11, 1874.

To all whom it may concern:

Be it known that I, WILLIAM J. BENNETT,

of Beaver Dam, county of Dodge and State of Wisconsin, have inventedcertain new and useful Improvements in Wash-Boiler Attachment, of whichthe following is a specification:

My invention relates to that class of washboiler attachments consistingof a perforated plate supported at any desired height above the bottomof the boiler, and provided at each end with a tube, perforated near thetop on the inner side, for the passage of the steam and suds; and thenature of my invention consists V in the construction of the perforatedplate, and also in a slide arranged in connection with each tube, toopen and close the perforations therein, as occasion may require, all ashereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichforms a part of this specification, and in which- Figure 1 is aperspective view of my washboiler attachment, one of the tubes beingpartially broken open to show the slide therein. Fig. 2 is alongitudinal vertical section of the same.

A represents a plate provided around its edge with a downward-projectingrim, B, and made of such size as to fit on the bottom of an ordinarywash-boiler. By means of a suitable instrument the plate A is cut with anumber of semicircular slots, to, the metal inside of each semicirclebeing bent slightly upward, forming lips b b, as shown. These slots andlips may be arranged in any desired manner, in transverse rows, the lipspointing from the center toward both ends, or otherwise, as may bedeemed most advantageous.

By this construction of slots and lips, even the finest fabric isprevented from passing through, and the perforations will not becomeclogged.

O 0 represent the tubes at the. ends of the plate A, which tubes may beof any desired form, closed at the upper ends, and provided on the innersides with perforations w as, for the passage of the steam and water, asis usual in this class of wash-boiler attachments. Inside of each tube 0is arranged a slide, D, held against the inner side of the tube by meansof a spring, G, or other equivalent mechanical device. The slide isprovided with a rod, 01, passing up through the end of the tube, bymeans of which the slide may be moved up and down, to open and close theperforations or. By closing these perforations the flow ofwater isstopped, While removing the clothes from the boiler.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is-- 1. The plate A, provided withthe semicircular slots at, and upwardly-bentlips l), for the purposesherein set forth.

2. The combination of the perforated tube G, slide D, with rod d and thespring G, all substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my invention I hereunto aflixmy signature this 28th day of November, 1874.
